AVB Out

The AVB Input and Output are on the same physical card but are represented in the Q-SYS design by an AVB Input Component and an AVB Output Component.

The AVB Output component provides an output up to 32 channels in 4 streams for devices supporting the AVB protocol. Other combinations of input/output are described in the Properties section below. Connection is made with CAT-5 / RJ-45 connector.

For hardware information, see CAN32 – AVB Audio Video Bridge Card.

Controls

Each control listed in the Analog and Digital sections, are one per channel.

Default / Range

Channels

The Channel tabs switch between channel ranges. The available ranges depend on the Input/Output count in the Properties. The controls are the same for each stream.

Default = Channels 1-8 / 9-16 / 17-24 / 25-32

Peak Output Level (dBFS)

Measures Peak Output level to the output device for each channel.

Range = -120 to 20

Status LED

This LED changes color to indicate the current status of the I/O-22 Output. See Status for the meanings of the various colors.

N / A

Status

Displays the current status of the amplifier both in text and color. The following is a list of possible status colors, and some example conditions.

Note: These conditions are examples, and may not be applicable to all components with a Status field.

OK – Green – (0) – Audio is good, hardware is good.

Compromised – Orange – (1) – Audio is good but a redundancy mechanism is active (one LAN down but the other is still up) or a non-fatal hardware problem exists (fans too slow, temperature higher than expected, etc.)

Fault – Red – (2) – Audio is not passing, or hardware is malfunctioning or mis-configured (amplifier power off, audio streams broken, wrong type of I/O Card installed, loudspeaker short circuit, etc.)

Missing – Red – (3) – A piece of hardware, defined in the design, has not been discovered. Audio is not passing through that piece of hardware.

Initializing – Blue – (5) – In the process of firmware, configuration update, and design start. Audio is obviously bad.

Not Present – Gray – A virtual component in the design, that is designated as Dynamically Paired, and Not Required ,has no hardware assigned to it.

Talker Streams

Control

Function

Default / Range

Stream Prefix

Allows you to enter a 12-byte hex number of your choice. Typically the FSID is derived from the MAC address of the AVB card.

N / A

Stream Prefix Set Button

After entering the 12-byte hex number in the Stream Prefix file, press this button to "set" that number is the ID

N / A

Stream <n> Full ID (FSID)

Read only. The FSID of each Talker Stream is shown here.

This is the stream Prefix with a 4-byte stream index appended.

You can copy this value and paste it into an AVB Input component's Full Stream ID field.

Talker Channels / Stream

You can have from 2 to 32 channels per stream.

If you select 32 (in or out) channels, and 2 channels per stream, the maximum number of channels is 24.

If you select 16 x 16 channels and 1 listener channel per stream, the inputs are limited to 14.

Listener Channels / Stream

You can have from 2 to 32 channels per stream.

If you select 32 (in or out) channels, and 2 channels per stream, the maximum number of channels is 24.

If you select 16 x 16 channels and 1 talker channel per stream, the outputs are limited to 14.
